the fiber optic microwave subcarrier multiplexing video transmission system using the domestic photoelectric products is introduced.The experiment of the first intermediate frequency FM FDM video signal from Asia satellite l was demonstrated.After the signal transmissing through 1.3 μm 38.78 km singlemode fiber link
and when the received optical power is -22 dBm
the C/N deterioration is smaller than 3 dB.When the recieved optical power is equal to -30 dBm
